They're celebrating 85 years of business Wednesday and are giving away Slurpees from 11 a.m. to 7 p.m. They expect to give away double the amount this year just because of social media marketing. During the Slurpee promo last year, sales on other items in the store rose significantly, according to our partner USA Today.

That's not the only promotion for free stuff this week that's spreading on social media.
